Smoke liO bore. @ne head 15 is adapted to bear against the inner end of the head 13 as explained, and the other head against the bottom or socket 8 of the mouthpiece, and said heads are provided with cut-away openings or notches 16 so that smoke drawn from the bowl may pass through extension 12, the adjacent notches 16 and be spread or expanded thereby to pass along the four sides of the corresponding head, and then pass through the bore 9` around the expander 14: and, in subdivided streams, pass the other head and through its to the bore ot the mouthpiece. It will be obvious that by thus subdividing the stream of smoke as it passes the two heads 15 successively, a better opportunity for the precipitation of nicotine and juices isl given and the smoke therefore will reach the tongue in a cooler state and uncontaminated by nicotine which will accumulate around and upon the expander and within the bore 9.

ritter suitable intervals, the smoker can clean a pipe o't this character sufiiciently by simply disconnecting the mouthpiece and section 3 from the stem section 2, and blowing through the mouthpiece, this action having the effect of keeping the notches of the expander clear of obstructions. If it is desired to make'this action more thorough, the extension 12, ifremovable, can be easily detached, and when it is desired to thoroughly clean the stem, the mouthpiece will also be removed so that the expander can be dropped out oi" the section 3 for scraping or washing, and to give better access to the bore of said section with a swab.

Through the protection aforded to the bore 5 by the extension 12, the bowl of the pipe will be. kept comparatively dry and sanitary, as before explained, and this statement oi course applies to the entire length oi stem 2.

A pipe of the character outlined possesses the features ol advantage set 'forth as desir- -ahle in the statement of the object of the invention, and it obviously can be modified in minor particulars without departing from the principle of construction and mode'o'f operation involved, or the spirit and scope of the appended claims.r

I claim:

1. In a smoking pipe, a stem having its bore of enlarged diameter between its points of communication with the bowl and the mouthpiece, and a smoke stream expander extending within the said enlargement and provided at its extremities with enlarged heads contacting at laterally-spaced points notches 1Gv with the wall of said enlargement of the bore to provide passages between the said heads and the wall of the stem and fitting at its ends over the portions of small diameter of the bore, the heads having projec tions to engage end walls of the stem and prevent the heads from closing the portions of small diameter of the bore; the said projections and the passages between the heads and enlarged portion of the bore permitting the smoke and juices to pass from the bore of the bowl end of the stem into the said enlargement, and the smoke to pass from the said enlargement into the bore of the mouthpiece.

2. In a smoking pipe, a stem having its bore of enlarged diameter between its points of communication with the bowl and the mouthpiece, anda smoke stream expander fitting within the said enlargement and at its ends over the constricted portions of the bore of the stem; the ends of the expander having notches to permit smoke and juices to pass from the bowl into the said enlargement and from the latter into the bore of the mouthpiece.

3. In a smoking pipe, a stem having a detachable intermediate section provided with a larger bore than and alined with the portions of the bore of the end sections, and a smoke expander fitting in the bore of the intermediate section, in alinement with the bores of the end sections, there beingcutaway portions on the expander to cause the smoke from the bowl to enter the interme diate section in a plurality of streams, and to pass from said section to the mouthpiece in a plurality of streams.

4. In a smoking pipe, a stem having a detachable intermediate section provided with a bore of larger diameter than the end portions of the stem, and detachably secured to the latter; said intermediate portion having a tubular extension within the bore at the end ot the stein adjoining the bowl, and a smoke expander fitting within the enlargement ot the bore and provided with enlarged heads dividing said bore enlargement at each end into a plurality of passages; there being cut-away portions on the expander for establishing communication between the boreot the portion adjoining the bowl and the said enlargement, and for establishing communication between the latter and the bore of the mouthpiece of the stem.

In witness whereof I hereunto athx my signature.
